Inquiry Regarding Efficiency Calculation with Zero Layer Thickness in Perovskite Solar Cell Simulation

[bmw8350]

hello to you all. I am currently using your software to simulate perovskite solar cells, and I have encountered an issue regarding the efficiency calculation when setting the thickness of a layer to zero. Despite the layer being set to 0 nm, the simulation still provides an efficiency value, and in some cases, it even appears higher than when the layer has a positive thickness. However, in practical experiments, this would result in an efficiency of 0% since the device cannot function properly without that layer.

Could someone kindly explain why this situation occurs in the simulation? Are there specific settings or parameters I should adjust to accurately reflect the absence of this layer and obtain more realistic results? I want to ensure that the model appropriately handles the missing layer, especially considering carrier transport and interface effects.

Thank you for your assistance!

Hi, If you attach your sim.oghma file that does not work I will take a look. If you respond to this message, then under the text box where you write your text there is an attachments tab. You might have to scroll down to find it. Best, Rod
